Improve in-flight connectivity to wireless networks.
In an age when being connected to the Internet means being connected to the wider world, we expect to have Internet access everywhere — including commercial airplanes, where passengers expect easy access to Internet servers, email and in-flight entertainment while airborne.
GORE Leaky Feeder Antennas keep passengers connected. Our antennas improve signal propagation while reducing the amount of hardware required on the plane. These antennas provide reliable connectivity to different wireless systems, including picocells for mobile phone coverage and access points for airborne Wi-Fi.
Ideal for both wide-body and single-aisle passenger aircrafts, Gore's antennas significantly reduce dead spots, enabling passengers to connect to wireless networks throughout the cabin.
The inherently flame-retardant materials used in the construction of GORE Leaky Feeder Antennas meet the flame and smoke toxicity specifications of FAR Part 25.1359(d) and Airbus ABD0031 without added flame retardants.
The engineered fluoropolymers used in the construction of GORE Leaky Feeder Antennas are inherently flame-retardant. They meet Airbus ABD0031 and FAR Part 25.1359(d) specifications for flame and smoke toxicity, which ensures reliable flame protection. These materials are also resistant to abrasion and cut-through, reducing the potential for damage during installation.
Reduced Costs for Wireless Access
Broadband technology used in aircraft generally requires separate equipment for each wireless protocol. GORE Leaky Feeder Antennas enable integrated hardware to run multiple protocols through a single antenna, reducing the quantity of wireless-N access points (N-WAPs) required to ensure signal coverage.
These lightweight antennas reduce equipment costs by offering a single solution that provides connectivity for a variety of electronic devices. Because of their durable construction, our Leaky Feeder Antennas don’t require any maintenance for the life of the aircraft, and this further reduces operating costs.
Features & Benefits
GORE Leaky Feeder Antennas are engineered to be superiorly reliable during flights and over time. Enabling this reliability are features like:
- uniform signal propagation for wireless access throughout the entire cabin
- reliable access across a broad range of frequencies with a single antenna
- reduced costs with single hardware set and cables that require no maintenance for the lifetime of the aircraft
- outstanding flame and smoke protection with inherently flame-retardant materials
- easy installation for new production and retrofit applications in both single-aisle and wide-body aircraft
- increased flexibility with rugged cut-resistant and abrasion-resistant construction
- reduced exposure to wireless radiation
With a single antenna installed along the length of the cabin, passengers can access wireless networks for their laptops, tablets, mobile phones and in-flight entertainment systems regardless of their location in the cabin.
These antennas dramatically reduce dead spots because of the proprietary technology that maintains excellent antenna gain and coupling loss over a broad range of frequencies and antenna lengths as measured according to IEC 61196-4, Free Space Method.
GORE Leaky Feeder Antennas are typically used in:
- wide-body aircraft
- single-aisle aircraft
- picocells for mobile phone coverage
- Wi-Fi 802.11 a/b/g/n/ac and WiMAX
Additionally, the antennas commonly support connectivity to Bluetooth, DECT, DECT2, Globalstar, GSM, IRIDIUM Sat, MMS, PDC and TETRA protocols.

Faster digital networks, more power performance, high-quality in-flight entertainment (IFEC), improved fuel efficiency, and less maintenance and downtime were some of the major themes at the Farnborough International Airshow held in London on July 11-17.
Reliable performance of microwave/RF cable assemblies with longer service life and reduced equipment downtime results in lower costs for testing in laboratory, production, and field test environments. A new white paper from W. L. Gore & Associates evaluates the durability and performance over time of several 18-GHz microwave/RF cable assemblies described as having a ruggedized construction with similar specifications.
W. L. Gore & Associates (Gore) has continuously expanded the company's microwave/RF solutions at higher frequencies by designing cable assemblies that are reliable and will perform over time, and Gore is now addressing industry requirements for enhanced performance in the 60-70 GHz range. At the 60-70 GHz range, there is increased need to maintain measurement accuracy, especially in Network Analyzers, Oscilloscopes, Analog Signal Generators, Communication Testing, Chamber Testing, and mm-Wave to name a few key applications.
W. L. Gore & Associates, Inc. (Gore) has been named the Vertical Impact: Military winner at the Excellence in Avionics Awards, honoring the high achievements of individuals, organizations, teams and projects that are elevating the aviation industry.
